2. XFree86 Project Licensing Policy

The XFree86 Project's basic licensing philosophy has always been summed
up as "You can do what you like with the code except claim you wrote
it." Expressed more formally, it means that the licenses acceptable
for code that makes up XFree86 must meet the following conditions:

The code must be redistributable by others in either source or
binary form.

Others must be permitted to modify the code, and to distribute
modified code or derived code without being required to pay a
licensing fee or other financial consideration to the copyright
holder.

Others must be permitted to distribute binary-only forms of the
code if they which to do so.

A range of Open Source and Free Software licenses meet these conditions.
The licenses in this document are examples of acceptable licenses.
Contributors to XFree86 are encouraged to choose the license type that
best suits them. If you have any questions about whether a specific license
fits in with the XFree86 licensing policy, please contact us.
